"I purchased these flats in grey for an additional 30% off in store. I'm not usually a flats type of person, but for only $24, who could resist?!These run true to size. I'm typically a size 6 or 6.5 for flats, but I opted for the 6.5 to have a little room for the back of my heels. They were very uncomfortable at the heel for the first day I wore them out (they were rubbing at my heel--ouch!), but a bandage quickly fixed that issue. The sole is comfortable enough that I didn't need an insert. They are short in the front, so part of your toes will show. Overall, a great purchase when I got it on sale!"
